High-Side Load Switch
ADP199
GENERAL DESCRIPTION
The ADP199 is a high-side load switch designed for operation between 0.9 V to 3.6 V. A load switch provides power
domain isolation, thereby helping to keep subsystems isolated
and powered independently, and enabling reduced power
consumption.
The ADP199 contains a low on-resistance, N-channel MOSFET
to minimize power loss, and supports over 500 mA of continuous
load current. The low 6 µA quiescent current and ultralow
shutdown current make the ADP199 ideal for battery-operated
portable equipment. The built-in level shifter for enable logic
makes the ADP199 compatible with many processors and GPIO
controllers.
In addition to high performance, the ADP199 occupies minimal printed circuit board (PCB) space with an area of less than
0.64 mm
The ADP199 is available in an ultra-small, 0.8 mm × 0.8 mm ×
0.5 mm, 4-ball, 0.4 mm pitch WLCSP.
